Table 18.12 Serial I/O

_______

Table 18.13 External interrupt INTi input

Note 1: Use the greater value, either (1/digital filter clock frequency X 6) or min. value.

Note 2: Use the greater value, either (1/digital filter clock frequency X 3) or min. value.

_______

Note 1: When the INT0 input filter select bit selects the digital filter, use the INT0 input HIGH pulse width

to the greater value, either (1/digital filter clock frequency X 3) or min. value.

_______

Note 2: When the INT0 input filter select bit selects the digital filter, use the INT0 input LOW pulse width to

the greater value, either (1/digital filter clock frequency X 3) or min. value.
